Second Network interface appeared after Fedora 34 update

Dear all,

Just upgraded to Fedora 34 from Fedora 33, running on a P14s Thinkpad with Ryzen 4750u.

Suddenly, a second Ethernet interface appeared, and once I connect the Eth cable, I cannot get connected to the network.

enp2s0f0: conectando (obteniendo configuración IP) to enp2s0f0
        "Realtek RTL8111/8168/8411"
        ethernet (r8169), 38:XX:XX:XX:XX:25, hw, mtu 1500

enp5s0: conectando (obteniendo configuración IP) to enp5s0
        "Realtek RTL8111/8168/8411"
        ethernet (r8169), 38:XX:XX:XX:XX:24, hw, mtu 1500

I have preserved the last two digits of my MAC addresses, note that the address of the first follows the second.

Best!
Joan

It turns out that this Laptop has two interfaces, but just one plug.

Problem appeared after Fedora 34 update, where the power control of ethernet seems to fail. I had to reproduce the fix from fatka/reptyr

i.e.: echo on > /sys/bus/pci/devices/0000:05:00.0/power/control
